The new web browser, which arrives just six weeks after Firefox 7, comes with Twitter search functionality and on-demand tab group loading.

"This update includes new features that make web browsing easier and give users and developers more control over how they customise their web experience," read a Mozilla statement.

The improved Twitter support enables users to search for hashtags and @ usernames to bring up pages on the social networking platform. This feature is expected to be welcomed by the Twitter community, who frequently report negative feedback on the site's own search function.

On-demand tab group loading rectifies a long-running issue, allowing the user to recall windows with multiple tabs open. Other new features include the option to uninstall third-party applications more easily and improved HTML5 support.

In addition to the launch of Firefox 8, Mozilla has revamped the Android version of the browser. "We want to make HTML5-based web apps as easy to use as native apps," said the platform holder.

"Firefox [now] lets Android users add icons for any bookmarked website or web app to the home screen and launch with just one touch."

Firefox 8 is available to download for Windows, Mac and Linux via the firm's website.
